I am having a problem with this code: List<Enemy> Player1 = getObjectsInRange( 2000,Player1.class); if(Enemy.size()!=0){ pointAtObject(Enemy.get(0)); move(6.0); } I have it in the act(). It is complaining and saying: cannot find symbol - method size()

You named your List Player1, not Enemy

Thanks! I fixed and now am getting a new error. List<Player1> Enemy = getObjectsInRange( 2000,Player1.class); if(Enemy.size()!=0){ pointAtObject(Player1.get(0)); move(6.0); } It is telling me that it cannot find symbol - method get(int)

List<Player1> Enemy = getObjectsInRange(2000,Player1.class);
if(Enemy.size()!=0){ 
     pointAtObject(Enemy.get(0)); move(6.0);
 }

You named your List Enemy, not Player1

List<Player1> Enemy = getObjectsInRange(2000,Player1.class); if(Enemy.size()!=0){ pointAtObject(Enemy.get(0)); move(6.0); } Now it is saying: cannot find symbol - method pointAtObject(Player1`)

cannot find symbol - method pointAtObject(Player1) can you imagine what that means? :D i think java cannot find the method pointAtObject Have you created this method in your class?

I got this off a source. This is all it came with and is what I currently have in my Enemy class. What should I do? //this is at the top of the page where it should be. import java.util.List; //this is in the act() List<Player1> Enemy = getObjectsInRange(2000,Player1.class); if(Enemy.size()!=0){ pointAtObject(Enemy.get(0)); move(6.0); } //this is down below in the main code, not called in the act() public int pointTo(int x, int y) { int dX = x - getX();//get distance between mouse's X and player's X int dY = y - getY();//get distance between mouse's Y and player's Y double rotation = Math.atan2(dY, dX); rotation = Math.toDegrees(rotation); return (int)rotation; } Thanks :D

If Enemy is an Actor, using its turnTowards(int x, int y) method I think should do the same as your pointTo method. If in fact you are using the pointTo method's return value for setting the Actor's rotation

//this is at the top of the page where it should be.
import java.util.List; 

public void act() {

	// here you get a list named 'Enemy' from type 'Player1'
	List<Player1> Enemy = getObjectsInRange(2000,Player1.class); 
	// if list isn't empty
	if(Enemy.size()!=0){  
		// call function pointAtObject with the first element
		// from list (the element is from type 'Player1')
		// but where is the function?!
		pointAtObject(Enemy.get(0)); 
		move(6.0);  
	} 
}

// the method may look like this
// it will accept a parameter from type 'Player1'
void pointAtObject(Player1 player) {

	// do something with 'player'



}
